Title:
ANTISKID CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JPS62152956
Kind Code:
A
Abstract:
PURPOSE:To make a decompression characteristic or the like at the time of antiskid control controllable to optimum conditions according to the turning behavior of a wheel, by installing a variable throttle device inclusive of a movable piston to be displaced in depending upon differential pressure, in at least the upstream of a hold valve in a controller bearing the above caption. CONSTITUTION:A controller bearing the above caption is provided with a normally-opened type hold valve 3 to be closed at the time of antiskid control side by side in the point midway in a braking hydraulic pressure transfer route 1 connecting an interval between a master cylinder M/C and a wheel cylinder W/C. Also it is provided with a normally opened type pressure reducing valve 4 to be closed at the time of the antiskid control, in the point midway in a pressure oil return route 4 to be bypassedly connected between a downstream position of the hold valve 3 and an accumulator Acc via a pump P. In this case, a pressure rate regulator 6 consisting of contraction percentage regulators 7 and 11 fixed each and movable pistons 8 and 12 and a decompression rate regulator 10 both are in stalled the upstream position of the hold valve 3 and the bypass side of a pressure reducing valve 2 whereby the desire end comes to fruition.
